Driving Through Standing Water - Volvo XC90 T8 TwinEngine Plug-In Hybrid Owner's Manual

Driving through standing water

The vehicle should be driven with extreme cau-
tion if it is necessary to drive through standing
water.
The vehicle can be driven through water up to a
depth approximately level with the floor at walk-
ing speed to help prevent water from entering
the differential and/or the transmission or dam-
aging electrical components.
•
If possible, check the depth of the water
before driving through it. Take particular care
when driving through flowing water.
•
Before driving through water, always select
Off Road
the drive mode to ensure that the
gasoline engine is running and to maximize
ground clearance.
•
After driving through water, apply the brakes
and check that they are functioning correctly.
•
Clean the electrical connections for trailer
wiring after driving in mud or water.
•
When driving through water, maintain low
speed and do not stop in the water.
CAUTION
•
Damage may occur to the engine, trans-
mission, electrical components, etc. if the
vehicle is driven through water higher
than its floor level. Be aware that waves
created by other vehicles could cause the
level to temporarily be above the vehicle's
floor level.
•
Damage to any components due to water
above the floor level, vapor lock or insuffi-
cient oil is not covered under warranty.
•
If the engine has been stopped while the
vehicle is in water, do not attempt to
restart it. Have the vehicle towed out of
the water and inspected by a trained and
qualified Volvo service technician.
WARNING
•
Avoid driving through standing or rushing
water. Doing so can be dangerous and it
may also be difficult to determine the
actual depth of the water.
•
If water cannot be avoided, after driving
through the water, press lightly on the
brake pedal to ensure that the brakes are
functioning normally. Water or mud can
make the brake linings slippery, resulting
in delayed braking effect.
